Casting on Fringe, J.J. Abrams' pilot for Fox, is nearly wrapped up, with two of the three leads now filled. Aussie actor John Noble ( The Lord of the Rings' Denethor) will play Dr. Walter Bishop, the institutionalized scientist a young female FBI agent must collaborate with to get to the bottom of a rash of paranormal activity, while Lance Reddick (a star on The Wire and a recurring player on the upcoming season of Lost) has been cast as the special agent who heads the division of Homeland Security that specializes in X-Files-type events. As reported the other day, Kirk Acevedo ( Oz) and Mark Valley ( Boston Legal) are also onboard.

Now we're just waiting on the G-woman.
